I went mad trying to learn pharmacology, pretty much tried to learn everything but stuff just wouldn't stay in my head!
Then I decided to learn by group rather than individual meds. What a difference! Most meds have clue endings as to which group they come from so it's easy to place them e.eg. "pril" for ACE inhibitors & "lol" for beta blockers. It all started to make much more sense & was easier to learn.
Anyway, LOL I hardly had any pharmacology questions in the actual exam, those I did have were nearly all "tick all that apply" so many of them probably didn't even count!
Still I'm now the most knowledgeable nurse on my ward in the UK when it comes to drugs!
